Температура повітря у Південному Розточчі

Abstract

The demonstration and analysis of the monthly and annual average air temperatures in Southern Roztochia for last 46 years are proposed. The meteorological data of the Roztochia landscapegeophysical station (RLGS) of Ivan Franko National University of Lviv have served as the starting material for this publication. The long-term value of the average air temperature in RLGS has been defined. The average temperature warming by 2 °C has occurred from 1970 to 2000 and the amplitude of fluctuations of average temperatures has increased since 2000. The fact of a gradual warming trend in the region Roztochia and the adjacent Small Polissia was confirmed as an attribute of the consequences of global warming and drainage reclamation during the XX century. The graphs for annual average, maximum and minimum air temperatures for last 46 years were concluded for the duration of 5 years at the seasons. The coldest period of research is the years 1969–1989 and the warmest ones are the years since 2000 and especially 2015. The parameters of extreme warming in 2015 were fixed in agriculture and water management. We are warning about the possibility of aridization of the territory as a result of the trend of warming. The ways of preventing of regional warming due to reducing the activity of drainage reclamation systems, conservation of forest and meadow vegetation are suggested. Key words: average air temperature, regional warming, extreme air temperature, Southern Roztochia.
